7. Security Considerations

This specification does not introduce any new mechanisms or security concerns beyond what is in the other documents it references. In WebRTC, video is protected using Datagram Transport Layer Security (DTLS) / Secure Real-time Transport Protocol (SRTP). A complete discussion of the security considerations can be found in [WebRTC-SEC] and [WebRTC-SEC-ARCH]. Implementors should consider whether the use of variable bitrate video codecs are appropriate for their application, keeping in mind that the degree of inter-frame change (and, by inference, the amount of motion in the frame) may be deduced by an eavesdropper based on the video stream's bitrate.

Implementors making use of H.264 are also advised to take careful note of the "Security Considerations" section of [RFC6184], paying special regard to the normative requirement pertaining to SEI messages.
